vIMPROVEMENTIN FILTERS.

Specification forming part of Letters Patent No. 126,926, dated May 2] 1872.

thcgother being of sponge; the said filters be` ing elevated a little above the bottoms of the pans, so that the settlings upon the said bot-V toms will not flow into them.

Figure l is a sectional elevation of my im proved Water iilter and cooler, and Fig. 2.. is a horizontal section ofthe same.

Similar letters of reference indicate corre spondin g parts.

A is a cylindrical vessel of sheet metal or other suitable substance open at the top, with a vertical partition, B, extending from top to bottom, and cutting oi' a small ice-chamber, C, from the main water-space D. In the latter is a pan, E, extending from the top down about half Way to the bottom, and having one -or more sponge filters in the bottom tightly packed in cork rings Gr,whicl1 are fitted snugly in the short cylinders H open at both ends.

I is another pan fitting in the top of E, and extending about half way to the bottom of it. This pan is also provided with lters K, preferably made of fine screen-Wire 5 but they may be made of sponge, if preferred. These are also fitted with cylinders H, which extend abeve the bottom and prevent the settlings from owin g along the bottom of the pan to the filter. L is a cock for drawing the filtered water.

Both the Wire-gauze and the sponge filters are applied so that they may be readily detached for cleaning and replaced again. The pans may also be removed from time to time for removing the settlings from the bottoms.

This simple apparatus provides a very eicieut filter that can be kept in good condition with very little care.

Having thus described my invention, I claim asnew and desire to secure by Letters Patent- The vertically-partitioned vessel A B, provided with pan E having sponge filters F G H, and pan I having wire-screen lters K H, arranged as and for the purpose described.

JAMES BRADY.
